SYSTEM. METHOD AND APPARATUS FOR INTEGRATION OF FIELD. CROP

AND IRRIGATION EQUIPMENT DATA FOR IRRIGATION MANAGEMENT

[001] RELATED APPLICATIONS

[002] The present application claims priority to U.S. Patent Application No. 62/945,268 filed Dec. 9, 2019.

[003] BACKGROUND AND FIELD OF THE PRESENT INVENTION [004] Field of the Present invention

[005] The present invention relates generally to an irrigation management system. More particularly, the present invention relates to a system, method and apparatus for providing full integration of field, crop and irrigation equipment data for irrigation management.

[006] Background of the Invention

[007] Modern field irrigation machines are combinations of drive systems and sprinkler systems. Generally, these systems are divided into two types depending on the type of travel they are designed to execute: center pivot and/or linear.

[008] Regardless of being center pivot or linear, common irrigation machines most often include an overhead sprinkler irrigation system consisting of several segments of pipe (usually galvanized steel or aluminum) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length. These machines move in a circular pattern (if center pivot) or linear and are fed with water from an outside source (i.e. a well or water line). The essential function of an irrigation machine is to apply an applicant (i.e. water or other solution) to a given location.

[009] Traditionally, growers will map a field using field scouting, satellite, unmanned aerial vehicle (UAV) and/or micro air vehicle (MAV) images. Additionally, deployed irrigation machines and active sensors provide continual streams of data. Each of these monitored factors impact crop yields. Independent of these factors, growers are also affected by the cost of the goods and services needed for crop production (e.g. water, electricity, fertilizer).

These costs continually change along with weather data and commodity pricing. At present, these groups of information are not integrated or easily displayed. Instead, the management and analysis of this data can be very expensive and require three or more software platforms to view and analyze the data. Additionally, growers are required to spend increasing amounts of time to manually combine data and calculate field irrigation requirements. [0010] In order to overcome the limitations of the prior art, a system is needed which can effectively integrate and display data from different sources. Further, a system is needed which can provide actionable data analysis for growers.

[0011] SUMMARY OF THE DISCLOSURE

[0012] To minimize the limitations found in the prior art, and to minimize other limitations that will be apparent upon the reading of the specifications, the present invention provides a system, method and apparatus for providing an irrigation scheduling module including a graphical user interface for providing irrigation scheduling data for a given field location.

[0013] According to a preferred embodiment, the irrigation scheduling module is configured to calculate and display an irrigation recommendation for a given set of forecast data. According to a further preferred embodiment, the irrigation scheduling display includes a representative shape in the form of a circle which changes from a full circle to a crescent shaped percentage of the full circle based on the field moisture status.

[0037] With reference now to FIG. 4, the input signals from the sensor systems are preferably received via a set of data collection inputs 132 and thereafter collected and stored in memory/ data repository 127. The data sources may include: system diagnosti c/BUS data 140; soil sensor inputs 142; climate sensor input 144; image sensor input 146; remote data inputs 148; and remote/MAV/satellite inputs 150. As data from each of the sources of the present invention may differ in format and data structure, the data is preferably transformed into a common format such as XML or other format so that the data can be subsequently mined, modeled and interpreted. According to a preferred embodiment, the data repository 127 preferably provides a common schema and archive for all sensor data in the system as well as for externally provided data along with any required input transformations, extended data dictionaries, and database designs that encompass all inputs. Since the data stored on the data repository 127 is obtained from a variety of tools, the data is preferably further processed to remove duplicated and/or conflicting data. This deconfliction of data is preferably resolved by a combination of data deconfliction methodologies such as rule based and machine learning tools which are provided via a data deconflicting engine 123 or the like. As shown in FIG. 7, once deconflicted, the soil/crop analysis module 133 preferably extracts data from the data store 127 and fuses the data with historic crop/weather data 134 and other inputs. Preferably, data fusion is accomplished using several technologies which may include Dempster/Schaeffer, Bayesian classifiers, neural nets, parallel coordinates, genetic algorithms, AI techniques and other classification schemes.

[0039] With reference now to FIGS. 5-6, the system may further include a net yield value module 135 which preferably operates to collect and analyze data related to crop health, crop growth rates, potential crop yields and operational costs. Example input variables may include: commodity pricing 138; weather data 164; crop growth data 165; resource pricing data 167; drive system data 140; and historic data 134. Preferably, the combination and analysis of data is continually processed and updated.

[0040] As shown in FIG. 6, the net yield value module 135 preferably analyzes the collected data using a net yield value algorithm 168 which includes several processing steps. According to a preferred embodiment, the net yield value algorithm 168 preferably processes the received data using regression analysis 172 to create models of future values for selected variables. According to a preferred embodiment, the models may include one or more commodity pricing curves 174, crop yield optimization curves 176 and resource pricing curves 178. These respective models preferably represent a projected set of future values for each variable over the course of a given growing season. Thereafter, the net yield value algorithm 168 preferably further applies mathematical optimization modeling 180 to the modeled curves to determine the optimal target crop yields, irrigation prescriptions and harvest scheduling. The optimization method used may include any mathematical optimization method without limitation. According to a preferred embodiment, artificial intelligence techniques may preferably be used such as evolutional algorithms or the like.

The optimized target crop yields, irrigation prescriptions and harvest scheduling are then preferably transmitted or accessed by the VRI module 129 for use in developing a target irrigation prescription for a given area.

[0041] As shown in FIG. 7, data output from the soil/crop analysis module 133, the VRI module 129, and the vehicle diagnostic systems 140 are each accessible via a user interface 182. The output data is preferably modeled and made available for presentation in a dashboard display that is focused on graphical and mathematical visualization of the data. The user interface 182 preferably provides an interface through which data generated by the present invention is transformed into predefined or user selectable visual representations as discussed further below. [0042] Referring now to FIG. 8, the system of the present invention preferably processes requests by extracting data, transforming it and displaying recommended and forecasted data through the requester’s web browser. FIG. 8 illustrates an exemplary interactive display incorporating a number of graphical user interfaces (GUIs) in accordance with the present invention. As shown, a first GUI display 184 includes a daily irrigation recommendation along with supporting information for the irrigation recommendation for given dates 189 (e.g. 09/06). In the example display 184, an example crop of “Peppermint” is shown along with an initial crop evapotranspiration rate (ETo) 186 and an irrigation depth 188 for the current date. An irrigation recommendation 192 is provided (e.g. irrigation depth in inches) along with a representative shape 190 indicating the percentage of field capacity remaining as discussed further below. Additional supporting information shown includes: degree days 194; current time 196; recommended irrigation speed 198; rainfall forecast 200 and recorded rainfall 202.

[0043] As shown in a second GUI display 185, present invention may display irrigation recommendations for a range of future dates 204 (e.g. 09/06 - 09/12). As shown, the display may include a daily irrigation recommendation 206 (e.g. irrigation depth in inches) along with a representative shape 208 indicating the percentage of field capacity remaining. As shown, the daily irrigation recommendation 206 may be superimposed over the representative shape 208 to provide an efficient view of the combined information. The field capacity 210 may also be represented numerically.

[0044] As show in each GUI display 184, 185, the irrigation recommendation may be printed inside or above a representative shape 190, 208 indicating the field moisture status for each day of the forecast. Preferably, the shapes 190, 208 may be based on a circle that changes from a full circle to a crescent depending on the soil moisture status. For example, less soil moisture (more irrigation required) may preferably be represented by a less complete circle shape for that day’s irrigation recommendation. According to further preferred embodiments, the date assigned 189, 204 to the recommendation may be provided above each irrigation recommendation. Below the irrigation recommendation, the printed soil moisture status may be numerically reported as a percent of field capacity (%FC) 210. Preferably, the irrigation forecast for any day can be expanded to display relevant crop and irrigation data by clicking on the irrigation recommendation or the shape(s) 190, 208. The shape(s) 190, 208 of the present invention may be colored and may also change in color, shade and/or intensity to indicate different levels of soil moisture. [0045] With reference to FIG. 9, an exemplary irrigation recommendation display 212 may include a chart 213 having rows of information for each day within a selected range. The chart 213 may include columns listing information for each date 214 including: crop evapotranspiration rate (ETc) 216; original field capacity 216; after irrigation field capacity 220; deficit 222; irrigation depth 224; rainfall forecast 200; scheduled irrigation amount 228; recorded rainfall 230; irrigation speed 232; irrigation start time 234; current time 236; and irrigation end time 238. The chart may further include one or more circle based shapes representing soil moisture status as discussed in detail above.

[0046] According to preferred embodiments, the user interface may preferably allow the user to manually input daily irrigation amounts. The system may also preferably receive and automatically input daily rainfall amounts received. In both cases, the displays of the present invention may preferably automatically update and display updated irrigation forecast data for a user-selected number of days ahead. Accordingly, the user may propose irrigation for a selected number of days ahead and visually see a comparison of the original irrigation forecast to the scheduled irrigation forecast. Further, the system may preferably compute and update the soil moisture deficit for each day and the irrigation required to fill the deficit each day of the selected period.

[0047] The scope of the present invention should be determined not by the embodiments illustrated, but by the appended claims and their legal equivalents.
